Single Status Condition

If the value displayed matches a value in the Status Condition column, it indicates only one parameter and its description.

Examples:

Status = 0, all OK ‐> front panel LED's GREEN

Status = 1, all OK, tape advancing ‐> blinking GREEN LED

Status = 128, machine is running, tape advance warning flag is set ‐> YELLOW

Multiple Status Conditions

If the Status displayed does not match a value in the table, it means that there are multiple parameters whose Status Conditions are added together, forming a sum that must be broken down by subtraction: find the largest value in the Status Condition column that does not exceed the Status value, and subtract it from the sum. Then Find the next largest value in the Status Condition column that does not exceed the remainder, and subtract again. Continue finding the next largest number and subtracting it until the remainder matches a value in the Status Condition column.

Examples:

Status = 289, which breaks down as follows: 289 – 256 = 33; 33 – 32 = 1; therefore, the Status Conditions are 256, 32, and 1. which mean ‐> machine is not measuring (1), LED calibration had errors in 1 or more (but not all) channels (32), and less than 5 tape advances are left (256)

Status = 145, which breaks down as follows: 145 – 128 = 17; 17 – 16 = 1; therefore, the Status Conditions are 128, 17, and 1. which mean ‐> machine is not measuring (1), LED calibration is in process (16), and less than 10 tape advances are left (128)
